LOCK.

Application led May `27, 1922. Serial No. 564,052.

To all whom t may concern:

Be it known that I, AUGUSTUS C. SAX- 'roN,.a citizen of the United States, residing at Chicago, Illinois, have invented certain new and useful Improvements in Locks, of

whichthe following is a specification.

My invention relates to that type of locks designed to prevent operation of the gear shift lever of a motor vehicle and among 3G the objects thereof lare to provide an improved structure of the character stated; to provide a structure which will positively lock the control lever in neutral position; to provide a structure which cannot, by any of the means ordinarily employed for that purpose, be rendered ineffective for the intended use; and such further objects, advantages, and capabilities as will later more fully appear.

My invention further resides in thecolnbination, construction, and arrangement of parts illustrated in the'ac'companying drawings and, While I have shown therein a preferred embodiment. of my invention, I desire the same to be understood as illustrative only and not as limiting said invention.

' In the drawings annexed hereto and forming a part hereof,

Fig. 1 is a broken planview'of my new construction, the control lever being shown .in section.

Fig. 2 is a longitudinal section substantially along the plane indicated by the line 2 1-2 Fig. 1.

a right angle to the plane parts 'for sustaining and maintaining the control lever in position and permitting the same to oscillate to any one of the several controlled positions. The lever,` ball seat 5 is heldin adjusted position with relation to Fig. 3 is a broken sectional elevation, ap- Y in the body 4 of the lock casing are\the` the body member 4L by` means of a screw 6 which is ordinarily screwed in tightly andl 11 up against the lever ball 12, as will be obvious. The ring 8 having been turned in until it tightly holds ring 7 in position f.

is locked in place by means of a bolt or bolts 18 which'pass through the body member Land into the ring 8 and are then finished off flush with the surface of the body member. A screw or screws 14C serve to hold the body member 4: in proper posit-ion onthe housing 1 and these screws are likewise finished yoff Hush with the surface of the lock. It will be Seen fromjthe above that when the parts have all been placed in position and the screws cut or broken off until their outer ends are just flush with the lock body, it will be practically. impossible' to removethe lock unless provided with the proper-equipment. It will also be necessary to have the lock free from the machine and where it can be secured within proper machineryv for operation.

`The lock body 4: is provided with an upwardly extending flange 15 having at its upper end an inwardly directed flange 16, parts 15 and 16 having their upper surface convex, the center of curvature being located at the center of curvature of the ball 12. A curved plate 17 whose inner surface has the same radius of curvature as the upper Surface of parts 15 and 16, surrounds the control lever 2 and moves therewith, sliding over the Vcurved upper face of said members. Outside off-lange 15 is a locking ring 18 which maybe raised `up into the path of plate 17 to prevent the same from lateral motion' in any direction.4 Encasing these members is a sleeve whichv is fastened to the body member 4 by means of screwthreadingandV then permanently locked in position by means of screw 6 referred to above, after the parts have been properly positioned.

The details of the locking mechanism are shown'most clearly in Fig. 4 from which it i riphery .vith-a s ubstant tools.' Y

It is 'ofcourse un erstood' that the speciiic ldescription of structure, set v'forth above may will be .seenthat a cam-plate 19 `provided with aplurality oif camsQO, preferably not less than 5 in number, cooperates with locking ring 18 to raise same into locking position vas shoi'vn inltigW 6. As indicated above, these parts are enclosed in a casing 2l Within which cam-plate 19 isrotatively justed until cams 2O accurately lit in the cam notches 22 in locking ringvlf .when this ring is in unlocked position, When the above noted adjusted position is attained, locking' ring; 323i is turned in to lock the lcamplate r9 iirinl fn' adjusted position.

The locking? ring,` 18 is provided in its pe- Y iv cylindrical perforation 2li in which slides a cylindrical pin 25. Pin 25I has al'pertoration 26 extending therethroughftor the .reception or a pin eX- tending from' the vface of block 28 pivoted von the inner end ot the'vr locki` cylinder. This bloc'lr 2S is secured to the end .of the .look cylinder'SO bymeans of a cani plate 29 having on one edge a (am 3l or" appropriate .size Vand shape. In the prese; t example this is shown as extending one fourth ot the Way aroundv the plate QSlaud' block y28 also er;- tends around one fourth of the plate 29. lt will therefore beseen that during the lirst halt revolution ot the lrey and cylinder cam 3l does: not* engage with either shoulder 32 vorshoulder Brot the bloei; 28, but during' the secondhalt revolution this block `will caused'to turn about the cylinder 1800.' As lWill bel obvious this movement will' cause loclringrring 18 to-turn about its airis,y thus ,causing its camV laces to rise up onthe 1carri laces et the cams 20. `Whenthis happens :ring'lS rises so that itsupper end comes incontact with the edgeof plate 17 thus preventing the same trom being moved i laterally. This plate 'i7 is held doivn in contact with flange lby means of a flange 3st at theuppercdge oit casing 21.

It ivi-llb'efseen-romthe above description that when the parts are all" adjusted into desired relation and secured in 'adjusted ipositions', it ivi-ll be next toimpossible to-get vthemout olisuchadj-usted positions Without completely destroying the loclr,y thev parts beingv-v made of `very vhardmaterial so that they'are not susceptible Vto attacks with'cold chisel, Sledge; hack-saw and other similar be departed from Without departing from the spi i of my invention as set forth' in this speciica ion and. the appended claims.
